Homework Statement
A jet engine gets it thrust by taking in air, heating and compressing it, and then ejecting it at a high speed. IF a particular engine takes in 20 k/g of air per second at 100 m/s and ejects it at 500 m/s calculate the thrust of the engine.
chriss #getmoney: thrust of the engine would be v right?
Homework Equations
i believe that the equation is Mv1 + Mv2 = V(Mv1+Mv2) and that the thrust = V .
